What They Do
Invinity Energy Systems focuses exclusively on vanadium flow batteries (VFBs), which are a non-lithium technology designed for utility-grade, long-duration energy storage. This technology is particularly aimed at integrating with renewable energy sources such as solar and wind, providing solutions for grid stability, energy arbitrage, and demand response (source: stockanalysis.com). Their core products include the modular Invinity VS3 and Endurium/Endurium Enterprise™ brands, which are factory-built, stackable systems that offer significant advantages such as zero thermal runaway risk and up to 30 years of cycling without degradation. This longevity translates to the lowest lifetime cost per MWh due to unlimited throughput and non-degrading power/energy decoupling (source: invinity.com). The batteries support configurations ranging from under 250 kWh to tens of MWh, catering to utilities and power producers for wholesale trading and ancillary services, as well as commercial and industrial sectors for peak shaving and grid independence (source: invinity.com). Their target markets span across Asia, Australia, Europe, North America, and Africa, with a diverse customer base that includes utilities, developers, and independent power producers.
Projects & Track Record
Invinity has successfully deployed or contracted projects totaling over 75 MWh across more than 40 sites in 17 countries on five continents. Notable completed projects include the installation of over 160 Avalon modules in various regions including North America, East Asia, Australia, and Europe since 2016, as well as significant contributions to the UK’s £41 million Energy Superhub Oxford project, which involved supplying VFBs alongside renewable energy sources (source: invinity.com). A key highlight in their recent project portfolio is the 8.4 MWh VFB delivery in 2023 to Elemental Energy for the Chappice Lake Solar Storage project in Alberta, Canada. This project integrates a 21 MWp solar array, enhancing grid stability with low-carbon dispatchable power (source: youtube.com). The company continues to expand its solar-plus-storage initiatives globally, with a robust pipeline supporting utility-scale, commercial, and microgrid applications, leveraging its multinational facilities for project delivery.
Recent Developments
Invinity has marked significant operational milestones, having discharged over 7 GWh of total energy from its batteries since 2022, reflecting its commitment to scaling deployments amid the ongoing energy transition (source: invinity.com). In 2023, the company secured a major contract for the 8.4 MWh Chappice Lake Solar Storage project, which was notable for being the largest flow battery of its kind at the time, coupled with a solar array to support grid operations (source: youtube.com). As of August 22, 2025, Invinity reported a stock price of 20.50 GBX and a market capitalization of approximately 0.07 billion GBP, indicating ongoing trading activity on the AIM market (source: stockanalysis.com). The company has not announced any major acquisitions or funding rounds post-2023, but it continues to emphasize its public market stability and growth potential, with Jonathan Anthony Marren serving as the current CEO.
Working There
Invinity employs approximately 150 staff across various roles, including engineering, operations, commercial/project development, and executive leadership. Key figures in the company include CEO Jonathan Anthony Marren, CFO Adam Howard, and COO Neil Lang (source: stockanalysis.com). The company hires across its global footprint, with headquarters in London focusing on commercial and executive positions, while manufacturing and engineering roles are based in Bathgate and Motherwell in the UK, as well as Suzhou in China. North American operations are centered in San Francisco and Vancouver, supporting project delivery and research and development (source: invinity.com).

We are at the beginning of a global energy transformation of a scale not seen in generations. A future low-cost, low-carbon electric grid, serving a world that electrifies everything, is within our reach.
The last remaining gap is breaking the link between electricity supply and demand. The lowest-cost, most sustainable sources of energy today come from intermittent renewable generation; but our homes, businesses and industries need electricity at the flick of a switch.
That gap can be closed by energy storage: Devices that store electricity when it is plentiful, then provide power back to the grid when it is needed. Solutions, including ones using lithium-ion batteries, are being deployed in massive numbers to start filling this gap. But so far, none of those solutions have proven the ability to deliver power any time, anywhere, over decades of service: The level of reliability we've come to expect, and that the future grid will need.
This is the biggest challenge in energy today. Invinity is at the forefront of finding a solution. And we need you to help us deliver it.
Developed, manufactured and delivered by our teams in Canada and the UK, Invinity's vanadium flow batteries (or "VFBs") can be installed anywhere and consistently deliver electricity as needed over a service life exceeding 30 years. Moreover, Invinity's VFBs are highly recyclable, don't rely on rare or conflict minerals, and won't catch fire.
Invinity is a global VFB leader, with over 190 megawatt-hours of its batteries operational or in construction for over 82 projects across 15 countries - more than any other emerging energy storage provider. We've deployed the largest flow battery systems in the U.S., Canada, Australia, and the UK. Along the way we've earned financial support from the UK Infrastructure Bank, the U.S. Department of Energy, and some of the world's leading institutional investors.
